RECEIVER.

Application filed June 2,

To all 107mm it may concern:

Be it known that I, OSCAR M. LnIor-r, a citizen of the United States,residing at Genoa, in the county of De Kalb and State of Illinois, haveinvented a certain new and useful Improvement in Receiver Mountings, ofwhich the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to a receiver mounting, and more particularly tomeans for mounting telephone receivers on head bands so as to provide aconvenient and efficient head set for radio use.

It isa purpose of the invention to provide means for supportingtelephone receivers adjacent the ears of the user with the face portionsthereof adjacent the ear lying in planes that are oblique to each other,whereby a tighter fit of the receivers or cars pieces to the head isobtained. Ordinarily the human head is narrower toward the front thereofthan toward the rear thereof, and it has been found that by arrangingthe receivers so that the faces thereof adjacent the ears extend at anoblique angle to each other, the head set will conform more accuratelyto the shape of the head of the wearer, and will provide a substantiallysound tight joint between the ears and the receivers.

It is a further purpose of the invention to provide means for carryingthe receivers which are adju'stably mounted on the head bands, and whichare'adapted to be held in any desired adjusted position, said receiverholding means being so constructed that the same will not turn relativeto the head band, whereby the diverging relationship of the receivers isnot disturbed in adjusting the receivers or ear pieceson the band.

Other objects and advantages of the i11- vention will appear as thedescription of accompanying drawings proceeds. However, I desire to haveit distinctly understood that I do not intend to limit myself to theexact details shown or described, but that I intend to include as partof my invention all such obvious changes and modifications of parts aswould occur to a person skilled in this art, and as would fall withinthe scope of the claims.

In the drawings:

MOUNTING.

1922. Serial No. 565,407.

Fig. 1 is a side elevational view of my improved head piece;

Fig. 2 is aninside elevation thereof;

Fig. 3 is an end view of the device;

1 is a section taken on the line 4-4 of Fig. 3;

Fig. 5 is a section taken on the line 5 of Fig. 4;

Fig. 6 is a perspective view of the receiver holding clip;

Fig. 7 is a view similar modified form; and

Fig. 8 is a view similar to Fig. 2 thereof.

Referring in detail to the drawings, in Fig. 1 is shown a head band 10of resilient material, which may be covered, if desired, with anysuitable covering material. The head band 10 is provided with slightlydeto Fig. 1 of a fiected ends 11 so as to prevent engagement of the endsof the band with the-head of the wearer in placing the device in position, and said band 10 is provided with slots 12 at the ends thereof.

Mounted in each of the slots 12 is the rearwardly extending screwthreaded stud 13, which is mounted on the enlarged central portion 14 ofthe receiver holding member 15. Said member 15 is provided with an arm16 having a right angularly extending end portion 17 which is providedwith a pivot stud or pin 18 projecting from the inner face of the arm,said pivot membcr 18 being held in place in any desired manner, Themember 15 is provided with an arm 19 which is provided with an offset at20 so as to throw the outer portion 19' of the member 19 out ofalignment with the member 16 and rearwardly thereof. The arm 19 isprovided with a right angularly extending portion 20 which is ofsubstantially the same length as the portion 17 and which is providedwith a stud or pivot member 21 similar to the member 18.

It will be noted that due to the offset 20 the pivot pin 21 is spacednearer to the main body portion let of the member 15 than the pivot pin18. The stud 13 as previously mentioned extends through the slot 12, andis screw threaded so as to screw threadedly receive the nut 22, said nut22 being adapted to clamp the member 15 in any desired position relativeto the band 10, it being evident that the stud 13 can be adjustedlengthwise of the slot 12 as desired.

Mounted between the pivots 18 and 21 are the receivers 23, saidreceivers being provided with suitable openings for receiving the pivotmembers 18 and 21, as is customary. It will be noted that due to thefact that the pivot member 21 is positioned nearer the band 10 than thepivot member 18, the forward ear engaging faces 24 of the receivers 23will extend at an oblique angle to each other, and that due to the factthat they extend atsuch an angle, said receivers will fit very closelyto the head of the wearer of the device, because the shape of the headis such that the head is narrower forwardly of the ears than rearwardlythereof. It is necessary in order to maintain the desired angle of thereceivers relative to each other at all times, that the members 15carrying the receivers do not swivel or turn in any direction relativeto the band 10. Accordingly the extensions 25 are provided on the widerportion 1% of the member 15, said extensions 25 being provided withrearwardly extending lips 26 which are adapted to enter the slot 12 soas to prevent any pivotal movement of the member 15 on the band 10, butpermit-ting sliding thereof in the slots 12 to adjust the members to anydesired positions lengthwise of the band.

If desired, instead of providing an offset in one arm of each oftheclips, the means shown in Figs. 7 and 8' may be used to turn thereceivers at an oblique angle to each other. In said figures the headband 10 is provided with the slots 12 for receiving the studs 13provided on the clips 15. The clips, instead of having one arm thereofoflset, are provided with similar arms 31, having similar angular endportions 32 carryingpivot pins 33 between which the re ceivers 23 aremounted. It will be noted that the faces 24; of said receivers extend atan oblique angle to each other and that said angularity is obtained bytwisting the head band 10 at 34 as will be clear from Figs. 7 and 8. Theclips are slidable on the band 10? inthe same manner as the clips 15 areslidable on the band 10 and said clips are provided with the members 26corresponding to the members 26 for preventing turning of said clips onthe band.

Having thus described my invention, what I desire to claim and secure byU. S, Letters Patent is:

1. A device of the character described, comprising a head bandoffiexible material,

a receiver supporting member non-rotatably' mounted directly thereon toproject laterally therefrom, and a receiver pivotally mounted on saidmember, the axis of said pivots extending at a fixed oblique angle tosaid head band.

2. A device of the character described, comprising a head band offlexible material, a receiver supporting member projecting laterallytherefrom and non-rotatably and longitudinally adjustably mounteddirectly thereon, and a receiver pivotally mounted on said member, theaxis of said pivots extending at a fixed oblique angle to said head bandfor any adjusted position of said supporting member.

Adevice of the character described, comprising a head band, a receiversupporting member slidably and non-rotatably mounted on said head bandto project later:

ally therefrom, and a receiver, said receiver being pivotally mounted onsaid member on an axis extending obliquely to said head band for anyadjusted position of said member. p

4. A device of the character described, comprising a head band offlexiblematerial, a receiver supporting member non-rotatably mounteddirectly thereon to project laterally therefrom and a receiver pivotallymounted on said member, said supporting member having an offset thereinwhereby the axis of said pivots extends at a fixed oblique angle to saidhead band.

5. A device of the, character described, comprising a head band, areceiver supporting member slidably and non-rotatably mounted onsaidhead band to project laterally therefrom and a receiver, said receiverbeing pivotally mounted on said member on an axis extending obliquely tosaid head band for any adjusted position of said member, said head bandhaving a slot therein and means on said receiver supporting memberentering said slot to hold said supporting member against rotation onsaid head band.

6. A device of the character described vcomprising a head band havingslots in the ends thereof, receiver holding members each having meansentering said slots to adjustably mount the same on said head band, apair of angular arms thereon, pivot pins on said arms and receiversmounted between said pivot pins, one of, said arms of each pair beingoffset transverse to said pivot pins whereby said receivers extend at afixed oblique angle to said head band.

In witness whereof, I hereunto subscribe my name this 12th day of May,A. D. 1922.

OSCAR M. LEIGH.
